One of my customers didn’t succeed to start the ASP.NET state service. Every time he tries to start the service an error message pops up. Well that service occupied a port to supply it services and the problem was that other process on the computer already uses that port. You can check the current port number and change it in the following registry entry:

Stoneware in the obscurity of System.WEB.UI the class LosFormatter is hiding. ASP.NET uses this class to serialize web controls state into string presentation inside hidden field inside the page Form. ASP.NET also uses LosFormatter on post back to de-serialize the hidden field back into controls. The class advantage is that it optimized for highly compact ASCII format serialization.  This class supports serializing any object graph, but is optimized for those containing strings, arrays, and hashtables.

More and more times I found myself arguing about ToString() as boxing. As you all know Tostring() is one of the object methods. Well, many programmers tend to believe that when they use ToSting() on value types (int, long, etc’) the CLR should box the value type into object to use the objects ToString(). That’s true if the value type uses the objects method. But, if value type override ToString() (and that’s what really happened) than boxing isn’t necessary since ToString() is part of the value type class.

While trying to define web application in IIS 6.5 (Longhorn’s version) for my ASP.NET application (by default ASP.NET use Cassini) I notice a new tab – “ASP.NET” that decorates the IIS MMC. This tab enables you to select the ASP.NET version that your application uses and display the web.config location. But the real fun begins when I press on “Edit configuration” button. A multi tab visual tool, which enable to visually editing of most web.config settings, popup. It’s really nice tool that enable to control and view web settings. I hope that IIS 6.5 will be shipped with Whidbey so we can get advantage of this tool.
